What is an umbilical hernia? An umbilical hernia is a bulge through the abdominal muscles in the area of the navel (belly button). The hernia may contain tissue from the abdomen, part of an organ (such as the intestine), or fluid.
Iliac crest contusion occurs due to bleeding of abdominal muscles and swelling. This can cause excruciating pain when the person tries to move his hip region. Bleeding can occur on the periosteum region of the bone resulting in inflammation and the muscles of the iliac crest would develop spasms.
1 doctor agreed: A number of things.: It is difficult for a person to tell exactly where pain at the left iliac crest comes from. A while it could be from the bone below the hip, it can from the soft tissues: muscles/ skin/ligaments/nerves. Additionally pain can be referred: from some other structures higher up.
